Bilateral Recession or Unilateral Recession-Resection as Surgery for Infantile Esotropia
Infantile esotropia is corrected in most cases by bilateral recession of the medial rectus muscles (BR) or by unilateral recession of the medial rectus muscle and resection of the lateral rectus muscle (RR). We compared the outcome of these techniques in a randomized prospective study.
Procedure: Bilateral recession
Procedure: Unilateral recession and resection
|Study Design:||Observational Model: Defined Population
Time Perspective: Longitudinal
|Official Title:||A Randomized Comparison of Bilateral Recession With Unilateral Recession-Resection as Surgery for Infantile Esotropia|
|Study Start Date:||January 1998|
|Estimated Study Completion Date:||December 2001|
We randomly assigned 124 patients (average age 5.8) from twelve participating clinics in Germany and the Netherlands to either BR or RR. Patients did not have demonstrable binocular vision at baseline. The angle of strabismus was measured pre- and postoperatively in a standardized fashion. The primary parameter to assess difference between BR and RR was the variation of the latent angle of strabismus at distance at three months postoperatively, secondary outcomes were reduction of convergence excess and binocular vision.
